Help with creating report

Hi

I am trying to create a report using SQL Report Builder to pull out stats from help desk database

I have not used report builder before and am struggling to get to grips with how to achieve my requirements

I want to show per help desk person a COUNT of calls opened and closed in a set time period - say a week

I'm at a loss as to when to specify what I need in the SQL query, or when to use expressions in the table etc

I can do a query to pull out a count of all tickets per help desk person e.g.

SELECT
  Work_Order_List.ID
  ,Work_Order_List.Status
  ,Work_Order_List.Assignee
FROM
  Work_Order_List

So do I then amend this query to specify date range

AND

Status e.g. Closed, Resolved, In Progress etc

OR do I do that in table in designer as a an expression

OR do I add it as a calculated field in my dataset

All help appreciated

Once worked out basics think I will then be okay
